Publish to stream B.

Answer: B

Explanation:

In Qlik Server Enterprise you can only import new applications through QMC.

Whenever you publish a new application to a Stream, it will automatically be "moved" there. So if you need this application to be also in another Stream, you need to duplicate this existing application and publish it again to another desired Stream.

This phenomenon occurs in an interesting way when we are developing a new application and we need to keep a copy in our Workflow in addition to publishing it. We don’t normally publish the developed application. We duplicate it and then publish the duplicate application in Stream.
